Kurz B ‐ Series Operations Guide 6– 4
Flow Meter Configuration
The status register bits are also used to report the diagnostic errors on the flow meter (function
code 02). This permits fast status polling along with the principle variable polling. Refer to
Chapter 4, Troubleshooting , in the Kurz Hardware Guide for a list of registers.
A drift check triggered through Modbus is a bit or coil write command with status. The amplitude
values (% 4 ‐ 20 mA scale) and the duration (seconds) for each drift check are available as read and
write registers. The results from a previous drift check (using volts measured from the internal
3.3 V programmable reference, not 4 ‐ 20 mA range) and percentage change are also available as
read registers.
